JsonPathParserError, when Objecttag contains only Number

[sm-ffm]

I've got the following Error:

jsonpath_ng.exceptions.JsonPathParserError: Parse error at 1:2 near token 1 (NUMBER)

I tried a lot, and it only raises, when Objectag only contains Numbers. I tried it with parsing / finding Data and Editing Data. Both raises Error.

Example Code:

`import json
from jsonpath_ng import jsonpath, parse

def jsonparser(Path, Json):
json_data = json.loads(Json)
jsonpath_expression = parse(Path)
Output = jsonpath_expression.find(json_data)[0].value
return Output

def jsonEditvalue(Path, Json, Value):
json_data = json.loads(Json)
jsonpath_expr = parse(Path)
jsonpath_expr.find(json_data)
jsonpath_expr.update(json_data, Value)
Output = json.dumps(json_data, indent=2)
return Output

jsonstring = """
{
"1" : {
"One" : "Data1",
"Two" : "Data2",
"Three" : "Data3"
},
"2" : {
"One" : "Data1",
"Two" : "Data2",
"Three" : "Data3"
}
}
"""
print(jsonparser("$.1.One", jsonstring))
print(jsonEditvalue("$.1.One", jsonstring, "DataNew"))
`
jsonpath-ng is the first Parser I used with that Kind of Issue.
